Hi, A little new to video but would like to research a few questions. 1. Recently using a basic Supergen but forgot to run the program "dolace" first. I am doing everything in DPaint interlace or Hi-Res anyway, so does it matter ? I mean I'm in interlace in one form or another. 2. I notice that after genlocking the graphic overlays are shifted to the RIGHT on the recorded Video. Why ? and how to correct ? I am not using an A1000 but an A2000HD 3. I really like the idea of the Toaster but would eventually like to do stuff in S-VHS or Hi-8. I don't suppose there is anyway to bypass the Toaster genlock in order to use a better (maybe external) one while still using all of the advantages of the Toasters' DVE and 3d program etc. Thanks in advance, Rocky

Rocky, I can help with two of your questions: 1) if you're running in interlace anyway, then the DoLace is not necessary. All DoLace does is convert all non-interlace screens into interlace for the output. 2) I'd guess your graphics shifting is due to a misaligned screen preferences. The monitor alignment you use on your normal Amiga monitor is likely not the same as for your video, so there is some shift. Solution? First, be sure the image on your video monitor is correctly centered (ie. if you were watching 'I Love Lucy' on it, it would look right), then send some Amiga out to the monitor (through your genlock, I'd guess?), and adjust the screen preferences until the graphics are correct for the video monitor. Finally, you can then try to adjust your regular Amiga monitor to center the graphics too. Actually I keep several sets of 'System-Configuration' files, including one just for recording to video, which is properly setup for my system. There may be an easier way than above, but it works for me! 3) I've heard that no genlocks will work with the toaster, but have never tried it myself. Good luck. –jp–seattle–

On number 2, the reason is that the Amiga RGB video out, and any genlock video out are going to be out of (horizontal) phase. Check your preferences. You'll prolly find that the display is shifted far to the right. Center the prefs, and the video output will be centered (close enough). Then, adjust the centering on your RGB monitor, and voila! If you have an Amiga RGB monitor, it may not be able to center the RGB image. I suspect that's why Commodore ships workbench with the prefs far to the right. I will have a utility called Video Tools on Tap that will center the display for you, among a bunch of other things. I will announce here when it is available (boy, will I announce <grin>) —Mike
